INEMTOR Be it-lmown that l, Lows STEINsmsena s of the city o'N'ew Yorin borough of Brook New York, have invented s new irnproved Insidetorl, of `which the following 1s :t full?V cleer, and exact description.

My invention relates to en insulator to be used in connection with high gmtential electric conductors employed for vsrious purposes, suchn as power transmission, wird less telegrsplly and telephony', and ordinary commercial service of various kinds.

In my new system I employ a number of indivi duel insulating units of different charecter. By sid i of my improved Weather shields, therein described, I sin enabled to Y render the individual units of comparatively small size, light Weightsnd low cost, as Well as adnptin' the units for carrying currents of exceptionally high potentiel.

My invention is adapted for limiting lesto age and preventing undesirable grounding of the current, either4 from conductors or from strnctures employed for support-ing conductors H i My invention else tends te prevent :eyeing :md p-ui-ictnring of the various individuali units.

Genelnlly spesicing7 my system comprel-xends s plurality of crossduer tubular insu laters with or Without weather shields, and e plurality of hoods 'or disk type insulators; also with' or Without Westner shields-.and snsljrended from s support.

lt will bennderstood that in some in stances 'I may dispense entirely with the nood or disk type-insulator units end ern lation to each ,other in any preferred naar nen e llvliile in the drawing show e. me'l red extending through the crossebm member, 'in other instances l muy employ e rod of ber, hard rubber or other suitable insnletng ma,n tcriel. Also, the crossbsr member may be of e. solid single mess of msterial. Again, two nods or bolts may be usedT enen extend into time ends of tile member, only s short distance and insulated from each o-tlren Spemzation of Letters fletent. swims@ im@ september "n, 191s. serien Nb. tasses `ble chain mede npof several units, moy loc extended indefinitely end the degree of 1ncitizen ot the ,United S tes, and e resident et sulntion stforded by the chain may be ina creased correspondingly. Moreover, the valyn,` in the county of Kings and Sli-'nte of rions parts may liev readily detached and rcplsced ny other parts, and the total number of parte may lue increased yor diminished at will other the originel struct-ure is finished.

This feature I regard as especially impor tent iniinstsnces Where, after the installation of the system, the voltage of the cnr- `rents is to be increased. My invention is readily sdapted for increase, to any desired extent, in the! vnltage,.tl1e various mechanical parts which l employ being of comperatively simple form, smell sise, lightweight and low cost.

My invention further comprehends the Acarrying the current from one unit toenother. My invention thus prevents serious lezikage and danger of arcing of the current, end as s result avoids damage to or destruction of the various insulator units.

In addition to the foregoing, my Innention contemplates various improvements in the speciiic kinds ot insulator nuits compris ing my systemn t Amengtbe several objects of my invenl tion are the following: I.

A disk shaped-hood or shield. 7 1s provided 'with e. thick central portion 8 and embedded Within this thick portion is o, basket 9 haw ing upon it, and integral with it, en arched portion l0, the letter being provided with. a threaded boss 11 projecting above the upper surfe/ee of the hood. The basket 9 .is of e annular form and extending through it is e screw bolt .12. Tbisiscrew bolt is provided With a frusta-@conical head 12 which prevents it from being drawn through the opening in the basket 9. A. clamp 13 is mede in holveswhich are pro vided with ears 14.-, and engaging these eers are screws 15 for holding the two halves of the clamp together. The screw l2 projects below the under surface of the hood and into threaded engagement with the upper portion of the clamp 13, whereby said clamp, and the parts supported thereby, are permitted a desirable degree of rotary move ment relatively to the hood. At'l is n link inode of a piece of twisted wire cable formed into o loop, the ends of the crible be ing twisted together and adjustably held by pressure of the clamp 13. At 17 is o. disk 'insulator which is provided centrally with s depending body portion 18 integral with it. Encircling this body portion and integral with. the disk 17 is a collar 19 hsivingv a. general annular form.

The body portion 18 is provided With un opening 2O extending diometricelly through it, :is shown more purtii'zularly in, Figs. 2

lund 3.y lExtending through the opening' 2O is n link 21 formed of @section of fiexible wire cable, the ends of which ere twisted tof brother nud ndjustnbly held by aid of a clump This clamp is made in halves provided respectively with eyes 23 through which eX- tend screwr bolts 24.-. The clump 22 is f lOl tributed as nearly equal as possible. The corrugations 36 tend to prevent the travel of moisture along: the tube 35, if, indeed, any moisture succeeds in reaching any portion of this tube. T he downwardly sloped portions of the rain shield, by guiding the rain obliquely downward and away from the centerof the system, tend, in a measure at least, to prevent the rainwater from reaching the tube and should a few drops accidentally obtain access to this tube the dry spaces between the corrugat-ions 36 prevent leakage of the current along the surtace of the tube 35. The spring portions 27 have their ends inclined upwardly toward the nuts i3 so that any water fallingr upon said inclined portions, from 'the parts 33 of the shield 31, or otherwise, will be led directly away from the nuts.

By connecting-a number of insulator units oi? the saine kind in series with each other, as yshown in the lower n'iiddle portion ot Fig. l, or by' alternating with disk and crossbar types, or by employing a series oie only the dish type insulators, the insulating strength ot the system as a whole may he increased at will. The vertical rod type insulator 1 6 with its corrugations serves to still further increase the insulating value of the system as a whole. This rod type insulator is oi a diameter which is small as compared with the length or width of the shields 3l, or the diameter of the disks 7.

-The advantage of this is that in casethe wind blows against the chain of insulators and causes the saine to swing, there is less liability for any part to .strike a neighboring; object if the diameter of the rod type insulator 46 (that is, the insulator nearest the conductor e9) be small.

The system as a whole may be used effectively without employing any of the rain shields, though it is. self evident that a larger factor of safety is provided and insulators of smaller sizes may he employed when rain shields are used with the systern.

From the foregoing it will be apparentthat there is a metallic chain extending throughout the length of the several units in such manner that. if any portion of the insulating material comprising the units is broken or destroyed, said metallic chain will be. effective to form a positive support for the conductor 49; for instance, if the insulator 17 bedestroyed throughy disintegration or otherwise, the loop 2l will corne to rest within the pocket formed by the loop 16; andv likewise, .if the composite insulator 535-4() be destroyed, then the collar 37 `will come. to rest in Contact with'the rod 4l. lt will be noted. also that throughout the greater portion of its extent the under surface of the hood i is in relatively. closed juxtaposition to the upper surface of the moisture laden air upward through the relatively sniall opening between the outerportions of the insulator and the hood. lt is also apparent that the loop 16 not only serves to reinforce the body portion of the insulator 17, but, that, troni its twisted formation, it is slightly elastic, enough so as to absorb sudden violent mechanical shocks and thus often serve `to save the insulator from destructionn l do notliinit myselif to the particular shape or forni for any part shown. Neither do l lirnit myself in all instances to the precise arrangement 'of the parts relatively to each other; nor to the employment in every instance weather shields on all of the units or on any of thein; nor do l'. limit myself to any particular material or ninterials to be used in iny system, or in the oonstruction ot any ot' Athe units thereof. l prefer, however, to employ tor the various insulating parts, the material known in this art as lilleetrose.1 E or the tube 35, how over, l may at tinies employ porcelain or glass, or such like material. For the metallic parts I generally prefer steel, though. other metals may be used with success,
